Benefits of technology

Prevents bleaching of medical supplies during disinfection and allows for visual confirmation of contents, maintaining the integrity and color of items like suture threads, while effectively sterilizing the packaging without compromising the materials used.

Problems solved by technology

The medical supplies are manufactured and contained in a packaging bag until use, which is not a constant period but storage is often a long time as well.
Moreover, disinfection is conducted using sodium hypochlorite, hydrogen peroxide, and the like in hospitals, and these disinfectants may penetrate into the packaging bag.

working example 1

[0040]Table 1 shows results from an experiment using four types of packaging bags A, B, C, and D. In Table 1, thickness (μm) is thicknesses of the films 11 and 12 constituting the packaging bag 10 for medical supplies, where 50+80 denotes that thickness of the film 11 is 50 micrometers and that of the other film 12 is 80 micrometers. Both of these films have used a film on which silica is deposited on each side.

Abstract

A method of packaging medical supplies includes overlapping a front film onto a back film, at least one of the front and back film being transparent and bacteria impermeable and does not transmit molecules as large as or larger than O2, extending a material that is gas permeable and bacteria impermeable along an opening side of at least one of the front and back film, and sealing the periphery of the front and back films except for the opening to form a packaging bag; inserting medical supplies in the packaging bag and then sealing the bag; sterilizing an interior of the packaging bag with EO gas injected through the material that is gas permeable and bacteria impermeable, removing the gas after sterilization and drying; and sealing the packaging bag so that the material that is gas permeable and bacteria impermeable does not communicate with the inside of the packaging bag.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation under 35 U.S.C. §120 of prior U.S. application Ser. No. 13 / 388,259, filed on Jan. 31, 2012, which is a National Stage entry under 35 U.S.C. 371(c) of International Application No. PCT / JP2010 / 062569, filed on Jul. 27, 2010, which in turns claims priority to Japanese Application No. 2009-179143, filed on Jul. 31, 2009, the entire disclosures of which are incorporated herein by reference.BACKGROUND[0002]The present invention relates to a method for packaging medical supplies.Background Art[0003]The medical supplies such as surgical suture thread and suture needles are contained in a packaging bag after production, and are sterilized and then stored. When using, the packaging bag is opened and the medical supplies are taken out and then used.[0004]The medical supplies are manufactured and contained in a packaging bag until use, which is not a constant period but storage is often a long time as well. Therefore...
